“This is a free software channel vocoder, which imposes vocal effects on a waveform. It can be used to make your voice sound “robot-like”, to create a singing synthesizer, to disguise your voice, and many other fun things.”

It’s quite easy to use and once you learn it, it gives you a good result. Maybe this program may come in useful for those who want that robot-voice for their brickfilm or something. :wink (just wanting to help)
